Measurement condition Ambient temperature: 23 °C Input power level: 0 dBm Terminating impedances: Input 680 Ω ║ -1 pF. Output 680 Ω ║ -1 pF. Construction and pin connection see page 2 Stability characteristics and packing see page 3 Characteristics Remark: Reference level for the relative attenuation arel of the TFS 167 is the pass band attenuation at the nominal frequency fN. The minimum attenuation in the pass band is defined as the insertion loss ae. The nominal frequency fN is fixed at 167,025 MHz without tolerance or limit. The values of relative attenuation arel are guaranteed in the whole operating temperature range. The frequency shift of the filter in the operating temperature range is included in the production tolerance scheme.
